Please Buy The Fastest Class A Motorhome on Earth
There’s something deeply satisfying about the idea of taking a motorhome from coast to coast. If there was ever a rolling domicile ready to take on the challenge of making that journey as fast as possible, it would be MoHo. This big block-powered 1977 GMC is currently the fastest Class A motorhome in the world, and now it can be yours thanks to Facebook Marketplace.
The Marketplace listing states this high-speed motorhome build was originally sponsored by Hot Wheels and its parent company Mattel in an effort to promote awareness about Charcot-Marie-Tooth disorder, a degenerative nerve disease. Not a show vehicle by any means, “MoHo” is currently the world’s fastest Class A motorhome with a certified top speed of 121.50 MPH, which was achieved out on the Bonneville Salt Flats.
At the heart of this Class A beast sits a 502 cubic-inch RamJet Chevy V-8 engine, which comes bolstered by modern fuel injection, a Magnaflow exhaust system, and a 125 shot of nitrous. The listing notes that the big block is capable of laying down 700 horsepower at 6000 RPM. To make the most of that power, the motorhome has been extensively modified from nose to tail. The floors, walls and ceiling have all been skinned in aluminum, while the exterior panels have been smoother for improved aerodynamics. A full chromoly roll cage extends the entire length of the vehicle, while a collapsible steering column and onboard fire suppression bring added peace of mind. Brakes and suspension components have been upgraded with a variety of GM-sourced parts, while a Ridetech air ride up front keeps things comfortable at speed. The rear end features a taller 3.07 gear set for top speed runs, helped along by a custom aero package.
The interior of this racer is currently rather sparse, with little inside behind the custom cockpit. There are currently a set of Twisted Stitch custom front seats, which sit behind a RacePak IQ3 Dash with data logger. Considering this bruiser is still street legal, there is an opportunity to refit some traditional motorhome accouterments. Just be sure to be mindful of the cage during that process.
The seller is asking $95,000 for the honor of sticking MoHo outside your house. That is certainly a lot of cash in the current market, but this is a world record holding machine after all. I’m sure that 121 mph has never felt so thrilling, but here’s hoping the next owner continues to push the limits of speed.
